Webcasts from the ACM Turing event. One is a presentation from Alan Kay named "Extracting energy from the Turing Tarpet". Alan uses the Frank system (remember Frankenstein monster) which is based on Squeak Smalltalk. As ever a very interesting presentation. Hope to find the time to watch also the others.
If you want to find it on the page click into the playlist in the video and scroll down to Alans talk.
